I've been watching this kit closely and I believe this is the lowest price
to date on any of the colors offered (white and black are always priced
higher than red). Keep in mind the zoom lens alone sells for $200. I
finally pulled the trigger on the red one. Couldn't pass up the additional
$26 savings over the black one...hope I won't look too silly.

Amazon just dropped the price of Pentax K-5:
http://www.amazon.com/gp/product/B0043M6F14/ref=ord_cart_shr?ie
DSLR body only to $599.95, it is temporarily out of stock as of now, but
can still be ordered. This camera is still ~$1400 everywhere else, so
probably a price mistake.
The body+lens kit is still $1588 on Amazon.

对焦速度赶上入门单反了,特别是弱光环境表现很好。
镜头做得更小了,特别是变焦。有14-45,和14-42等。
有大光圈镜头了,定焦有了一大批F1.8和F1.4,基本满足日常拍摄对背景虚化的要求。
芯片高感有了一个突破,1600可用了,配大光圈定焦,可以应付大多数晚上室内灯光的
人像拍摄了。
最后就是相机做得好看了。特别是Olympus推出的E Pen系列机身和镜头。
下一步应该是大光圈变焦镜头的突破,Olympus马上要推一个新的。
还有就是要把价格降下来。等产量上去了以后,应该会降。
最后M43可能是实用性,便携性和价格一个比较好的平衡点。
我还是看好E-P5。
同时愤愤为什么一堆APS革命机厂商不好好琢磨吧镜头做小,对焦做更快。当然M4/3镜
头小轻,马达推动的效果更快一点,所以的对焦快。

来自主题: PhotoGear版 - 科普:为什么要买数码单反?
给准备入门的人看的。大家也一起来集思广益:
为什么要买dslr?
0. 爱好:
你喜欢摄影。你喜欢专业摄影师摄影时候的酷(苦)样子。
1. 更快:
你是否看到很精彩的场面,但是等你打开dc,准备拍摄的时候,发现已经结束了?或者你
是否看到精彩的镜头,但
是按下快门以后,发现lcd上的照片不是你想要的那个样子?或者你一下子拍了好多张,
但是无法忍受一张和一张
之间的延迟?那么买dslr吧。
2. 更准:
你拍过运动中的东西么?例如骑车的人,运动的车,飞鸟...你是否发现用dc的时候很难
抓住画面,把对象抓得清
晰?那么买dslr吧。
3. 更广:
你是否看到美丽的风景但是手中的dc无法尽收眼底?或者你已经退到了退无可退的地方,
但是你要拍的东西还是缺
了一个角?那么买dslr吧。
4. 更长:
同样,你是否喜欢拍摄月亮,拍摄飞机?是否发现dc中的飞机月亮都太小太不清晰了?那
么买dslr吧。
5. 暗处更容易:
你是否发现晚上或者室内dc不用闪光灯就没有方法拍清晰?或者在博物馆里看到一幅非常
美丽的名作,却禁止使用
闪光灯,等到你拍下来回来放到电脑上看,发现拍糊了?那么买dslr吧。

其实这篇文章分析得还是有道理的,但是一定要突出强调professional这个限定词,另
外,如果能够就对焦精度和DSLR的对比展开说说就更信服了。
其实FF Mirrorless的市场就是焦距200mm以下,拍拍家庭照,满足一下时代弄潮人的优
越感,由此引申的啥革了DSLR的命都是瞎扯淡。这个和10年前DSLR与film胶片之争完全
不一样,DSLR能够革film的命不仅仅是相机本身,更重要的原因是digital在后期的优
势太大了,这点很多人没有认识到,于是一个mirrorless出来就整天喊革命革命。M43
或者APSC的mirrorless和DSLR是互补关系,FF mirrorless和DSLR就像是自动档vs手动

有一个经典的说法:若想要一个男人破产,就送他一台相机,并引领他走上摄影
之路。这句话虽然有些偏颇但的确不无道理。后来的发烧之路让我发现一跌入数码之后
,发烧程度便以指数级增长了。
04年初的时候我还在玩F3和F4,殊不知数码单反领域已经掀起革命了。03年夏天
的300D已经预示着DSLR普及大潮的来临,而我却还没有买DSLR的意识,一是觉的胶片不
错,二是看了当时的D100要1500刀,比我F3加七只手动头的价格都贵,所以根本不用考
虑了。虽然已经在网上不断看到DSLR的作品,而且相当不错,但那时DSLR对我来说似乎
依然很遥远。
局面很快就改变了:附近的冲洗店突然搬迁,除了walmart (还不洗slides)基本上找不
到别的冲洗的地方,拍胶片变的突然麻烦起来。另一个则是Nikon推出了新DSLR-D70,
虽然我看过之后对之不太感冒,觉的太业余,但N家用户似乎极其兴奋,屋脊上快炸了
锅。这时我的GF(前两天才发现GF一直是N家粉丝)不知怎么知道了消息,结果就开始
在我旁边开始敲打了,主要是她不满我身边机身镜头一堆,而她只有一个4500,于是便

这么小的CMOS,画质能高到什么地方去啊?如果画质不好的话,谁会去考虑对焦的问题?
懒得敲字了,copy一个 mobile01上面跟我一样观点的帖子
“我認為如果Nikon真的這樣子想
那他們失算了
很多擁有DSLR的人,其實是很希望有性能比美DSLR的隨身機的(像是我)
這不代表買了隨身機就不買DSLR了,畢竟操作上還是差太多,NIKON把隨身機市場跟DSLR市場混在一起,認為是互斥的,我認為很不智
D3100/D5100/D90/D700畢竟還是DSLR,他們吃不到隨身機的市場,因為體積還是太大
想用單眼的會去買單眼,想買隨身機的還是會去買隨身機
況且如果Nikon這樣的考量是正確的
現在推的這機子,不是APSC就算了,連4/3聯盟都比不上,這樣子是要怎麼跟S家還有P家拼市場?
Nikon現在這樣做,消費者又不是笨蛋,去買NEX跟GF就好了,外型一樣漂亮、片幅還比較大,到底是要怎麼搶市場?
實在搞不懂N家在想什麼”

来自主题: PhotoGear版 - 单反为啥整出个白平衡问题来?
白平衡问题不只存在于DSLR, 在小DC 和彩色胶片中一样存在白平衡的问题。 归根究
底,白平衡的问题起源于彩色胶片或 DSLR 中的Sensor 对彩色的感知能力和人眼/人
脑对色彩的感知能力不同造成的。 具体来说,对于人的眼睛来说,光线就是光线,晴
天的阳光和阴天的阳光除了强度不同外,在色彩上是没有太大的不同的。 但是,彩色
胶片或者digital sensor 对光线的颜色是非常敏感的。 对于DSLR 来说,晴天的阳光
和阴天的阳光在色彩上是有很大区别的。穿过云层或薄雾的阳光要比万里无云直接照射
的阳光偏蓝,人眼看不到,可是彩色胶片或sensor 能“看到”这种蓝色,并把他纪录
下来。 在实际摄影中, 这就给摄影者造成困扰。比如,在多云的天气拍摄山峰上的白

这令人想起Pentax 另一著名的光学设计师 -- 平川 纯 先生,他们两个年龄相仿,都
是于90年代开发了Pentax 一些著名的镜头而出名。平川先生今年48岁,远未到退休的
年龄。作为现在的Pentax专利持有人Hoya 在日本专利厅2010年获准的最后一件平川氏
开发的镜头专利是在2008年申请的。
泉水 隆之 和 平川 纯 两位都曾经是Pentax 历史上的顶级光学设计师之列的人物, 相
机爱好者中知名度甚高。
在整个90年代至21世纪初年,泉水氏开发了许多相机镜头光学专利,其中包括象 FA*

来自主题: PhotoGear版 - 关于APSC革命机,我实在搞不太懂
为什么革命机会比低端单反成本低?我觉得革命机的优势无非是:和DSLR比:体积,造
型。和DC比:可换镜头,画质。价格我觉得是次要的。
对于已有DSLR用户来说,革命机需要带来些普通DSLR办不到的事。N1的大像素密度就是
这样一个东西。还有的可以是连拍,高速视频。
取代低端DSLR有可能,但要看受众。如果是现在的DSLR用户,未必会习惯革命机的操控
和取景方式。对现在的DC用户,小巧,轻便和造型可能比画质上的一点点优势更有吸引
力。
